Description
GE 44A751101-G01 VME Bus Backplane / Rear I/O Interface
The GE 44A751101-G01 is a legacy GE industrial control hardware component associated with VME-based control systems. Available secondary-market references describe it as a VME bus backplane / backplane support component, but the public documentation located for this exact part number is inconsistent: some suppliers incorrectly describe it as a Mark VIe I/O baseplate or generic control module.
For procurement, the exact nameplate and physical configuration should be checked before treating 44A751101-G01 as a Mark VIe terminal base.

GE 44A751101-G01
Product Overview
The 44A751101-G01 should be treated primarily as a hardware interconnect/backplane component, rather than an intelligent controller or standalone I/O module. A GE-focused industrial automation reference specifically describes the part as a VME bus backplane circuit-protection/interface component, while another supplier identifies it as a VME backplane support assembly.
There are also recent supplier pages describing the same part as a Mark VIe rugged I/O baseplate. However, those pages provide conflicting technical descriptions and include unsupported specifications such as channel counts, redundancy, sampling rates, and certifications. Those claims should therefore not be used as authoritative specifications for purchasing or engineering substitution.
Application and Compatibility
For a legacy GE control cabinet, the 44A751101-G01 may be associated with a specific VME hardware arrangement. Compatibility should be verified using the complete assembly identification and the existing cabinet drawing or system BOM.
Before replacement, check:
| Check Item | Reason |
|---|---|
| 44A751101-G01 part number | Confirms the base assembly |
| G01 revision | Hardware revisions may differ mechanically or electrically |
| VME slot / connector arrangement | Determines physical and electrical compatibility |
| Existing GE system | Confirms the intended platform |
| Adjacent boards/modules | Backplane wiring and bus allocation must match |
| Terminal or cable arrangement | Prevents incorrect field wiring |
| Nameplate and assembly markings | Helps distinguish similar GE legacy assemblies |
Lifecycle Considerations
The part appears to belong to GE’s legacy industrial control inventory, and current availability is primarily through surplus and specialist automation-parts channels. Several current listings still offer the exact part number, but an official GE lifecycle document establishing a precise discontinuation date for 44A751101-G01 was not located in the sources reviewed.
For critical installations, retaining a correctly identified spare can be useful because mechanically similar VME assemblies are not necessarily electrically interchangeable.
Important Identification Note
A search for 44A751101-G01 produces materially conflicting descriptions. One source calls it a VME bus backplane, while another calls it a Mark VIe I/O baseplate. Because of that conflict, I would not publish specifications such as 24 VDC input, 16 channels, dual redundancy, 2,000 VAC isolation, SIL certification, or MTBF for this part without an OEM drawing or nameplate-confirmed source.
FAQ
What is GE 44A751101-G01?
It is a GE legacy industrial control hardware assembly associated in available references with VME-based control hardware.
Is it a programmable controller?
There is insufficient reliable evidence to classify the exact G01 assembly as a standalone CPU/controller. Available references more strongly support an interconnect/backplane function.
Is 44A751101-G01 a Mark VIe I/O terminal base?
Some current reseller pages describe it that way, but those descriptions conflict with other references identifying it as VME hardware. This should be verified against the physical unit and GE documentation before using that designation.
Can it be replaced by another GE VME backplane?
Not without checking the exact connector, slot, wiring, revision, and system configuration.
What information should be supplied when requesting a replacement?
Provide GE 44A751101-G01, the complete nameplate information, photographs of the assembly and connectors, and the GE control-system model or cabinet reference.
